The phrase signifies that a parcel has departed its origin point and is en route to its final destination. It indicates the package is currently moving through the carrier’s network, which might involve various stages such as transportation between facilities, sorting, and potential transfers to different vehicles or locations. For example, if an online order shows this status after leaving the warehouse, it means the delivery service has possession and is actively progressing it toward the recipient’s address.
This status update is important because it provides assurance that the delivery process has commenced and offers an estimated timeframe for arrival. Knowing the item is actively moving through the system can reduce anxiety about potential loss or delays. Historically, tracking was unavailable, leading to uncertainty once an item was shipped; the ability to monitor progress offers transparency and control to both sender and receiver.
